Intraosseous hemangioma (IH) in the maxillofacial area is a very uncommon neoplasm. Here, the authors show an exceptional case not previously reported in the literature of a 65-year-old man who presented with a pathological mandibular fracture following a facial trauma that was the first sign of an occult cavernous IH. Complete excision of the tumor in the mandibular ramus reduced the risk of severe bleeding and prevented long-term recurrence, whereas immobilization of the fracture obtained an excellent functional result. This clinical report highlights the possibility that a previously unknown primary IH may debut as a pathological fracture and the importance of differential diagnosis in this location.

Background: On January 26, 2010, our team performed a facial transplant for a patient with neurofibromatosis type 1. We detail the perioperative surgical strategies for the composite tissue allograft (CTA) of the lower parts of the face to restore a severe defect after excision of bilateral massive plexiform neurofibromas. The main distinctive feature included an innovative provisional heterotopic transplantation (PHT) technique of the facial allograft to the femoral vessels before its final orthotopic transplantation., Case Report: A 35-year-old Caucasian man received a CTA of the lower two-thirds of the face, including a chin osseous segment. The face was obtained from a non-heart-beating donor. The sequence of microsurgical procedures began by performing a PHT of the CTA to the recipient's femoral vessels in the right thigh. Intraoperatively, he experienced considerable blood loss that required transfusion of 24 units of packed cells. Surgical revision was required at day 7 to remove an extensive hematoma in the right side of the CTA. The maintenance immunosuppressive regimen included steroids, mycophenolate mofetil, and tacrolimus., Conclusion: We have reported a case of successful provisional transplantation of a human facial allograft onto the thigh as an alternative technique in human face transplantation. PHT was a reliable alternative procedure to obtain the facial allograft from a cadaveric donor., (Copyright © 2011 Elsevier Inc. All rights reserved.)

A cementoblastoma is rare, benign, and of odontogenic ectomesenchymal origin, usually associated with the roots of the first mandibular tooth. We present an unusual case of one that involved the roots of the first and second maxillary molars, extended into the maxillary sinus, and was associated with a displaced unerupted third molar. The initial presentation was misleading and resulted in inadequate management. The definitive diagnosis had not been established until 2 years later.

Dental anomalies can be classified in different groups: anomalies of volume, anomalies of number, anomalies of form, anomalies of position and anomalies by union. Of the latter, we distinguish between fusion, alveolus-dental gemination, concrescence, coalescence and anchylosis. Gemination is more frequent in the anterior teeth, although it can also affect the bicuspids and molars, being an anomaly of infrequent union (prevalence 0.5%). We present the case of a young male patient age 19, without medical antecedents of interest, that goes to consultation for repeated inflammatory accidents at level of the inferior left retromolar area. These episodes are caused by a semi-impacted inferior third molar that is fused to a supernumerary fourth molar, sharing its roots, crown, pulp chambers and canals. After the appropriate radiologic study and suitable planning, the semi-impacted third molar was extracted under local anaesthesia and without any other complications during or after the operation.

Odontogenic carcinomas of the maxilla are classified as malignant ameloblastoma, ameloblastic carcinoma or primary intraosseous carcinoma. The term 'ameloblastic carcinoma' is used to describe those ameloblastomas in which there is histological evidence of malignancy in the primary, recurrent or metastatic tumour. Three cases of ameloblastic carcinoma with an unusual location in the maxilla are presented here. Histologically, the lesions were characterized by typical zones of ameloblastoma as well as zones with anaplastic transformation. The authors review the literature describing the clinical and histological presentation and the treatment of this rare tumour.

Fifty-nine children younger than 16 years with mandibular fractures were studied by age, sex, type of fracture, cause, methods of treatment, and complications. The cases were divided into three age groups. The male-to-female ratio was 2.9:1. Motor vehicle accidents were the most common cause of mandibular fractures. Associated injuries were more common in young children. The condyle was involved in 43.3% of fractures. Intermaxillary fixation was the most common treatment used. Complications appeared to be rare.
